A-4 Precautions for Using the Network
Configurator on Windows XP, Win-
dows Vista, or Windows 7 or Higher
Better firewall security for Windows XP (SP2 or higher), Windows Vista, and Windows 7 or higher has
increased the restrictions for data communications. Before connecting the Network Configurator and
an NJ/NX-series CPU Unit and starting communications through the following procedures, you may
need to change the settings of the Windows firewall as described in this section.
• If you select Option - Select Interface - Ethernet I/F.
• If you select Option - Select Interface - NJ/NX Series Ethernet Direct I/F.
• If you select Option - Select Interface - NJ/NX Series USB Port.
Precautions for Correct Use
The main function of the firewall is to prevent illegal access from external sources (e.g., the In-
ternet). The purpose of changing the firewall settings through this procedure is to connect the
Network Configurator to an NJ/NX-series CPU Unit. If your computer is connected to an in-
house network, make such changes only after confirming that they have no security impact on
the network.
